Biology

Physiology

Rhyhorn's body consists of gray, rocky plates. Rhyhorn has four short legs and and triangle-shaped head with a single, short horn.

Gender differences

A female has a shorter horn.

Special abilities

Rhyhorn most well known method of attack is to charge straight into things. A charging Rhyhorn can knock a trailer flying. Rhyhorn can also use various Rock and Ground attacks. Rhyhorn can also learn elemental attack, but these type of attacks aren't very strong when used by a Rhyhorn (save for the Elemental Fangs). Rhyhorn is one of the few Pokémon capable of learning Megahorn.

Behavior

One can say that Rhyhorn has rocks for brains because it can only remember one thing at a time. A perfect example of this is whenever a Rhyhorn starts charging, it'll forget why it did so in the first place.

Habitat

Rhyhorn live in open plains and mountain ranges.

Pokédex entries

Gen	Game	Pokédex entry
I	Red	Its massive bones are 1000 times harder than human bones. It can easily knock a trailer flying.
	Blue
	Yellow	A Pokémon with a one-track mind. Once it charges, it won't stop running until it falls asleep.
	Stadium	Its bones are 1,000 times harder than human bones. Using its durability and strength, it can destroy tall buildings.
II	Gold	It is inept at turning because of its four short legs. It can only charge and run in one direction.
	Silver	It doesn't care if there is anything in its way. It just charges and destroys all obstacles.
	Crystal	It can remember only one thing at a time. Once it starts rushing, it forgets why it started.
	Stadium 2	It is inept at turning because of its four short legs. It can only charge and run in one direction.
III	Ruby	Rhyhorn runs in a straight line, smashing everything in its path. It is not bothered even if it rushes headlong into a block of steel. This Pokémon may feel some pain from the collision the next day, however.
	Sapphire	Rhyhorn's brain is very small. It is so dense, while on a run it forgets why it started running in the first place. It apparently remembers sometimes if it demolishes something.
	Emerald	Once it starts running, it doesn't stop. Its tiny brain makes it so stupid that it can't remember why it started running in the first place.

	LeafGreen	Its massive bones are 1000 times harder than human bones. It can easily knock a trailer flying.
